Thermal-siphon phenomenon and thermal/electric conduction in complex networks

The Role of Thermal Conduction in Accretion Disks with Outflows

In this work we solve the set of hydrodynamical equations for accretion disks in the spherical coordinates (r,θ,ϕ) to obtain the explicit structure along θ direction. We study a two-dimensional advective accretion disc in the presence of thermal conduction. We find self-similar solutions for an axisymmetric, rotating, steady, viscous-resistive disk. We show that the global structure of an advec...

Analysis of Paradoxical Phenomenon in Thermal Sensation

“Thermal Referral (TR)” and “Thermal Grill Illusion (TGI)” are known as illusions of thermal sensation, have been well studied. In a previous study, the experiment using two thermal-tactile stimulations to the forearm revealed that those illusions simultaneously occurred. On the other hand, in the experiment result, a few subjects perceived a hot stimulation as a cold sensation or a cold stimul...

Thermal Conduction in Simulated Galaxy Clusters

We study the formation of clusters of galaxies using high-resolution hydrodynamic cosmological simulations that include the effect of thermal conduction with an effective isotropic conductivity of 1/3 the classical Spitzer value. We find that, both for a hot (Tew ≃ 12 keV) and several cold (Tew ≃ 2 keV) galaxy clusters, the baryonic fraction converted into stars does not change significantly wh...

Thermal conduction in classical low-dimensional lattices

Deriving macroscopic phenomenological laws of irreversible thermodynamics from simple microscopic models is one of the tasks of non-equilibrium statistical mechanics. We consider stationary energy transport in crystals with reference to simple mathematical models consisting of coupled oscillators on a lattice. The role of lattice dimensionality on the breakdown of the Fourier’s law is discussed...
